Abstract
The method and apparatus for a secure RFID system provide a secure environment that the passwords are not known by a large number of operators and a reader ceases to operate if it is taken away from its authorized operator. The secure RFID system consists of tags, readers, authentication cards, and digital signature cards. The passwords are stored in the authentication cards and cannot be read by typical operators. The reader ceases to operate if the ticket in the authentication card expires or it is separated from the paired wireless authentication card. The authenticity of the tag data is ensured by using the signature card.
